How to include background into R plot?

My code:

x <-sample(1:1484)
y <-sample(1:1484)


library(hexbin)
cols <- colorRampPalette(c("darkorchid4","darkblue","green","yellow", "red") )
plot(hexbin(vel1,res1),colorcut = seq(0,1,length.out=24),colramp = function(n) cols(24))

Counts in the legend are from one to seven(e.g).How to include zero(white) in a legend?

You could change the mincnt argument to 0 and add "white" to the colramp function, adjusting the number of colors returned from your cols function:

plot(hexbin(x,y), colorcut = seq(0,1,length.out=24), mincnt = 0,
    colramp = function(n) c("white", cols(n - 1)))
